Guys, I am struggling for two days now, maybe someone could help.

I have 6 x Sapphire RX 580 Nitro+ 8 GB and I am not able to use 6 of them. My bios is modded properly and they work fine if I use up to 4 cards in a rig. But once I get more than 4 cards - I have cards visibility problem.

I have tried numerous drivers options, blockchain drivers work the best, but they only get 4 cards max to work (for some reason, they work if the patch is no applied).

I have also tried configuring motherboard bios, disabled secure boot and switched PCI-E to Gen2.

Is there any possibility that my motherboard (Asus H170) is not able to take on more than 4 cards? One of the power connectors is not plugged in (Molex/M2).

Has someone else experienced this? Does this look like a purely driver issue?
